鲁西南煤田含煤地层的层序地层单元划分

在前人研究的基础上，运用层序地层学的理论和方法，采用钻井岩心剖面和测井资料进行综合分析、对比和追踪的方法，确定层序界面和划分层序地层单元。结合研究区陆表海盆地沉积地层和陆相盆地沉积地层的特点，以及海平面变化特征，分析了二叠系沉积体系并建立了鲁西南煤田二叠系层序地层格架。重点对层序Ⅲ的上部层序单元进行了精细划分。

The Sequence Stratigraphy Subdivision of the Coal-bearing Strata in Luxinan Coalfield

On the basis of the study of Predecessors and by means of the principle and method of the sequence stratigraphy, the seguence interface is determined and the units of seguence stratigraphy are classified by employing the methods of synthetic analysis, comparison and Trace of drilling core sections and logging data. And on the basis of the characters of sedimentary sequences of the epicontinental basin and the continental basin, a detailed analysis on Permian sequence of Luxinan coalfield delta sediment is carried out. In the study, the change of sea level is used. The sequence stratigraphic framework is established. A detailed subdivision of upper part of sequence ID is carried out.
